Hits syncronization

[Mark Miller <ma...@gmail.com>]

Does the Hits class need to use a Vector for it's cache? Is the cache 
somehow shared among threads or should this be an ArrayList to avoid 
synchronization costs? Also, I do not see any backing array size 
initialization. Is this because the default of 10 is optimal? Am I wrong 
all over the place?

The Vector in Hits (Document, RAMDirectory and many more places) are
artifacts from the early days of Lucene (and Java). There has been
some discussion on if they should be replaced or not, but never got
anywhere.

You can safely change it to a JCF-list of your preference.
